DETAILED DESCRIPTION OF THE DISCLOSURE

Some embodiments of the present disclosure are directed to verifying a reliability of sensor data received from a mobile device. More particularly, certain embodiments of the present disclosure provide methods and systems for verifying a reliability of sensor data received from a mobile device of a user based at least in part upon a receipt of sensor data from an application that is configured to transmit sensor data in response to the mobile device being in a vehicle that the user is driving.

I. One or More Methods for Determining a Status of a Mobile Device According to Certain Embodiments

FIG. 1 is a simplified diagram showing a method 100 for verifying a reliability of sensor data received from a mobile device of a user according to certain embodiments of the present disclosure. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In the illustrative embodiment, the method 100 is performed by a computing device (e.g., a server 406 that is communicatively coupled to the mobile device). However, it should be appreciated that, in some embodiments, some of the method 100 is performed by the mobile device.

The method 100 includes process 102 for receiving a first set of sensor data at a first time from an application installed on a mobile device of a user, process 104 for receiving a second set of sensor data at a second time from the application, process 106 for determining whether the mobile device is in a vehicle that the user is driving during a time interval between the first time and the second time based at least upon the first set of sensor data and the second set of sensor data, and process 108 for transmitting a notification to the mobile device indicating that the application does not work properly in response to the mobile device not being in the vehicle that the user is driving during the time interval.

Although the above has been shown using a selected group of processes for the method, there can be many alternatives, modifications, and variations. For example, some of the processes may be expanded and/or combined. Other processes may be inserted to those noted above. Depending upon the embodiment, the sequence of processes may be interchanged with others replaced. For example, although the method 100 is described as performed by the computing device above, some or all processes of the method are performed by any computing device or a processor directed by instructions stored in memory. As an example, some or all processes of the method are performed according to instructions stored in a non-transitory computer-readable medium.

Specifically, at the process 102, the first set of sensor data includes one or more types of sensor data that was collected and/or generated by one or more sensors of the mobile device according to some embodiments. For example, the one or more types of sensor data include a first type for accelerometer data, a second type for gyroscope data, a third type for location data, and a fourth type for magnetometer data. The application that is installed on the mobile device is configured to transmit a first set of sensor data. For example, the application broadcasts the first set of sensor data to be received by nearby devices and/or directly transmits the first set of sensor data to a destination computing device (e.g., a server that is communicatively coupled to the mobile device). In response, the computing device receives the first set of sensor data at the first time.

In the illustrative embodiment, at the time when the application was installed on the mobile device of the user, the application is configured to transmit one or more types of sensor data in response to a determination that the mobile device is in the vehicle that the user is driving. In such embodiment, the first set of sensor data includes information related to a user activity (e.g., driving behavior). As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

According to some embodiments, the first set of sensor data indicative of the user driving behavior is collected from one or more sensors associated with the user’s mobile device. For example, the one or more sensors include any type and number of accelerometers, gyroscopes, magnetometers, location sensors (e.g., GPS sensors), and/or any other suitable sensors that measure the state and/or movement of the mobile device. In certain embodiments, the first set of sensor data is collected continuously or at predetermined time intervals. According to certain embodiments, the first set of sensor data is collected based on a triggering event. For example, the first set of sensor data is collected when each sensor has acquired a threshold amount of sensor measurements. In other words, the sensor measurements may indicate that the mobile device is in a moving vehicle.

According to certain embodiments, the application is configured to transmit the first set of sensor data periodically every first predetermined time interval when the application is triggered by a predetermined event. In other words, the application may work properly in the background but may not transmit any sensor data until the predetermined event occurs. As an example, this reduces a battery power consumption and preserves battery life. For example, as discussed above, the predetermined event is a driving event. According to certain embodiments, the application determines the driving event based on the sensor data collected or generated by the mobile device. Additionally or alternatively, the application receives an input from the user that indicates that the user is driving according to certain embodiments. However, it should be appreciated that, in some embodiments, the application periodically transmits sensor data every predetermined time interval.

At the process 104, the application that is installed on the mobile device is configured to transmit the second set of sensor data that was collected and/or generated by one or more sensors of the mobile device according to some embodiments. For example, the application broadcasts the second set of sensor data to be received by nearby devices and/or directly transmits the second set of sensor data to a destination computing device (e.g., a server that is communicatively coupled to the mobile device). In response, the computing device receives the second set of sensor data at the second time. In the illustrative embodiment, the second set of sensor data is a set of sensor data that is received from the mobile device by the computing device subsequent to receiving the first set of sensor data. In other words, the second time follows the first time by a time interval. It should be appreciated that, in certain embodiments, the second set of sensor data includes sensor data that has been collected or generated from the same sensors of the mobile device that generated the first set of sensor data.

According to certain embodiments, the second set of sensor data includes information related to a user activity (e.g., driving behavior). As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

According to some embodiments, the second set of sensor data indicative of the user driving behavior is collected from one or more sensors associated with the user’s mobile device. For example, the one or more sensors include any type and number of accelerometers, gyroscopes, magnetometers, location sensors (e.g., GPS sensors), and/or any other suitable sensors that measure the state and/or movement of the mobile device. According to certain embodiments, the second set of sensor data is collected based on a triggering event. As discussed above, in the illustrative embodiment, the application is configured to transmit a set of sensor data when the application is triggered by driving event (i.e., the predetermined event). According to certain embodiments, the application determines the driving event based at least upon sensor data collected and/or generated by one or more sensors of the mobile device and/or user input. In other words, the application may work properly in the background and may not transmit any sensor data until the predetermined event occurs. As an example, this reduces a battery power consumption and preserves battery life.

At the process 106, the computing device determines whether the mobile device is in a vehicle that the user is driving during a time interval between the first time and the second time based at least upon the first set of sensor data and the second set of sensor data received from the mobile device. As discussed above, when the application is initially installed on the mobile device, the application is configured to only transmit the sensor data that was collected and/or generated by the one or more sensors of the mobile device while the mobile device is in a vehicle that the user is driving. In other words, theoretically, the sensor data that was received from the application should represent sensor data that was collected and/or generated by the mobile device while the mobile device was in a vehicle. However, in real life, the sensor data received from the application may not be reliable for various reasons. To verify that the application is working properly and that the set of sensor data received from the application is reliable, the computing device determines whether the first set of sensor data and the second set of sensor data were generated and/or collected while the mobile device was indeed in a vehicle.

At the process 108, in response to the determination that the mobile device is not in the vehicle that the user is driving during the time interval, the notification is transmitted to the mobile device indicating that the application does not work properly. In other words, according to some embodiments, the set of sensor data does not adequately represent the driving behavior of the user. As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

FIGS. 2A, 2B and 2C are simplified diagrams showing a method 200 for verifying a reliability of sensor data received from a mobile device of a user according to certain embodiments of the present disclosure. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In the illustrative embodiment, the method 200 is performed by a computing device (e.g., a server 406 that is communicatively coupled to the mobile device). However, it should be appreciated that, in some embodiments, some of the method 200 is performed by the mobile device.

The method 200 includes process 202 for receiving a first set of sensor data at a first time from an application installed on a mobile device of a user, process 204 for receiving a second set of sensor data at a second time from the application, process 206 for comparing second accelerometer data of the second set of the sensor data with first accelerometer data of the first set of the sensor data to determine a first change during a time interval between the first time and the second time, process 208 for determining whether the first change satisfies a first predetermined condition, process 210 for comparing second gyroscope data of the second set of the sensor data with first gyroscope data of the first set of the sensor data to determine a second change during the time interval, process 212 for determining whether the second change satisfies a second predetermined condition, process 214 for comparing second location data of the second set of the sensor data with first location data of the first set of the sensor data to determine a third change during the time interval, process 216 for determining whether the third change satisfies a third predetermined condition, process 218 for comparing second magnetometer data of the second set of the sensor data with first magnetometer data of the first set of the sensor data to determine a fourth change during the time interval, process 220 for determining whether the fourth change satisfies a fourth predetermined condition, process 222 for determining whether all of the first, second, third, fourth predetermined conditions are satisfied or all of the first, second, third, fourth predetermined conditions are not satisfied, process 224 for determining that the mobile device is in the vehicle that the user is driving during the time interval in response to determining that the all of the first, second, third, fourth predetermined conditions are satisfied, process 226 for determining that the mobile device is not in the vehicle that the user is driving during the time interval in response to determining that the all of the first, second, third, fourth predetermined conditions are not satisfied, process 228 for transmitting a first notification to the mobile device indicating that the application does not work properly in response to the mobile device not being in the vehicle that the user is driving during the time interval, process 230 for updating or adjusting an amount of insurance discount, and process 232 for transmitting a second notification to the mobile device indicating that the amount of insurance discount has been updated or adjusted.

Although the above has been shown using a selected group of processes for the method, there can be many alternatives, modifications, and variations. For example, some of the processes may be expanded and/or combined. Other processes may be inserted to those noted above. Depending upon the embodiment, the sequence of processes may be interchanged with others replaced. For example, although the method 100 is described as performed by the computing device above, some or all processes of the method are performed by any computing device or a processor directed by instructions stored in memory. As an example, some or all processes of the method are performed according to instructions stored in a non-transitory computer-readable medium.

Specifically, at the process 202, the first set of sensor data includes one or more types of sensor data that was collected and/or generated by one or more sensors of the mobile device according to some embodiments. For example, the one or more types of sensor data include a first type for accelerometer data, a second type for gyroscope data, a third type for location data, and a fourth type for magnetometer data. The application that is installed on the mobile device is configured to transmit a first set of sensor data.

In response, the computing device receives the first set of sensor data at the first time.

In the illustrative embodiment, at the time when the application was installed on the mobile device of the user, the application is configured to transmit one or more types of sensor data in response to a determination that the mobile device is in the vehicle that the user is driving. In such embodiment, the first set of sensor data includes information related to a user activity (e.g., driving behavior). As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

According to some embodiments, the first set of sensor data indicative of the user driving behavior is collected from one or more sensors associated with the user’s mobile device. For example, the one or more sensors include any type and number of accelerometers, gyroscopes, magnetometers, location sensors (e.g., GPS sensors), and/or any other suitable sensors that measure the state and/or movement of the mobile device. In certain embodiments, the first set of sensor data is collected continuously or at predetermined time intervals. According to certain embodiments, the first set of sensor data is collected based on a triggering event. For example, the first set of sensor data is collected when each sensor has acquired a threshold amount of sensor measurements. In other words, the sensor measurements may indicate that the mobile device is in a moving vehicle.

According to certain embodiments, the application is configured to transmit the first set of sensor data periodically every first predetermined time interval when the application is triggered by a predetermined event. In other words, the application may work properly in the background but may not transmit any sensor data until the predetermined event occurs. As an example, this reduces a battery power consumption and preserves battery life. For example, as discussed above, the predetermined event is a driving event. According to certain embodiments, the application determines the driving event based on the sensor data collected or generated by the mobile device. Additionally or alternatively, the application receives an input from the user that indicates that the user is driving according to certain embodiments. However, it should be appreciated that, in some embodiments, the application periodically transmits sensor data every predetermined time interval.

At the process 204, the application that is installed on the mobile device is configured to transmit the second set of sensor data that was collected and/or generated by one or more sensors of the mobile device according to some embodiments. For example, the application broadcasts the second set of sensor data to be received by nearby devices and/or directly transmits the second set of sensor data to a destination computing device (e.g., a server that is communicatively coupled to the mobile device). In response, the computing device receives the second set of sensor data at the second time. In the illustrative embodiment, the second set of sensor data is a set of sensor data that is received from the mobile device by the computing device subsequent to receiving the first set of sensor data. In other words, the second time follows the first time by a time interval. It should be appreciated that, in certain embodiments, the second set of sensor data includes sensor data that has been collected or generated from the same sensors of the mobile device that generated the first set of sensor data.

According to certain embodiments, the second set of sensor data includes information related to a user activity (e.g., driving behavior). As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

According to some embodiments, the second set of sensor data indicative of the user driving behavior is collected from one or more sensors associated with the user’s mobile device. For example, the one or more sensors include any type and number of accelerometers, gyroscopes, magnetometers, location sensors (e.g., GPS sensors), and/or any other suitable sensors that measure the state and/or movement of the mobile device. According to certain embodiments, the second set of sensor data is collected based on a triggering event. As discussed above, in the illustrative embodiment, the application is configured to transmit a set of sensor data when the application is triggered by driving event (i.e., the predetermined event). According to certain embodiments, the application determines the driving event based at least upon sensor data collected and/or generated by one or more sensors of the mobile device and/or user input. In other words, the application may work properly in the background and may not transmit any sensor data until the predetermined event occurs. As an example, this reduces a battery power consumption and preserves battery life.

At the processes 206-220, the computing device determines whether the mobile device is in a vehicle that the user is driving during a time interval between the first time and the second time based at least upon the first set of sensor data and the second set of sensor data received from the mobile device. As discussed above, when the application is initially installed on the mobile device, the application is configured to only transmit the sensor data that was collected and/or generated by the one or more sensors of the mobile device while the mobile device is in a vehicle that the user is driving. In other words, theoretically, the sensor data that was received from the application should represent sensor data that was collected and/or generated by the mobile device while the mobile device was in a vehicle. However, in real life, the sensor data received from the application may not be reliable for various reasons. To verify that the application is working properly and that the set of sensor data received from the application is reliable, the computing device determines whether the first set of sensor data and the second set of sensor data were generated and/or collected while the mobile device was indeed in a vehicle.

In the illustrative embodiment, the first sensor data includes first accelerometer data corresponding to the first time, first gyroscope data corresponding to the first time, first location data corresponding to the first time, and first magnetometer data corresponding to the first time. The second sensor data includes second accelerometer data corresponding to the second time, second gyroscope data corresponding to the second time, second location data corresponding to the second time, and second magnetometer data corresponding to the second time.

Specifically, at the process 206, the first change in the accelerometer data during the time interval between the first time and the second time is determined by comparing the first accelerometer data and the second accelerometer data. For example, the first change indicates a change in movement of the mobile device during the time interval. According to some embodiments, the first accelerometer data is used to detect a first linear acceleration of movement of the mobile device corresponding to the first time, and the second accelerometer data is used to detect a second linear acceleration of movement of the mobile device corresponding to the second time. As such, according to certain embodiments, the first change indicates a change in the linear acceleration of movement of the mobile device.

At the process 208, the computing device determines whether the first change satisfies the first predetermined condition. For example, the first predetermined condition indicates one or more changes in the movements of the mobile device that are expected when the mobile device is in a vehicle while driving. According to some embodiments, the first predetermined condition is determined based on historical sensor data of other users. For example, the historical sensor data includes accelerometer data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes accelerometer data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the first predetermined condition is tailored to the user of the mobile device. For example, the first predetermined condition is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM - 9 AM and 5 PM - 6 PM), 5 days (Mondays to Fridays) a week, the first predetermined condition is determined based upon the accelerometer data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the first predetermined condition is determined based upon the accelerometer data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the first predetermined condition is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical accelerometer data and/or information received from the user. According to some embodiments, the first predetermined condition is defined and provided by the insurer associated with a vehicle of the user.

At the process 210, the second change in the gyroscope data during the time interval between the first time and the second time is determined by comparing the first gyroscope data and the second gyroscope data. For example, the second change indicates a change in rotational position and/or angular velocity of the mobile device during the time interval. According to some embodiments, the first gyroscope data is used to detect a first rotational position of the mobile device corresponding to the first time, and the second gyroscope data is used to detect a second rotational position of the mobile device corresponding to the second time. As such, according to certain embodiments, the second change indicates a change in the angular velocity of the mobile device.

At the process 212, the computing device determines whether the second change satisfies the second predetermined condition. For example, the second predetermined condition indicates one or more changes in the angular velocity of the mobile device that are expected when the mobile device is in a vehicle while driving. According to some embodiments, the second predetermined condition is determined based on historical sensor data of other users. For example, the historical sensor data includes gyroscope data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes gyroscope data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the second predetermined condition is tailored to the user of the mobile device. For example, the second predetermined condition is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM 9 AM and 5 PM - 6 PM), 5 days (Mondays to Fridays) a week, the second predetermined condition is determined based upon the gyroscope data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the second predetermined condition is determined based upon the gyroscope data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the second predetermined condition is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical gyroscope data and/or information received from the user. According to some embodiments, the second predetermined condition is defined and provided by the insurer associated with a vehicle of the user.

At the process 214, the third change in the location data (e.g., GPS data) during the time interval between the first time and the second time is determined by comparing the first location data and the second location data. For example, the third change indicates a change in location of the mobile device during the time interval. According to some embodiments, the first location data is used to detect a first location of the mobile device corresponding to the first time, and the second location data is used to detect a second location of the mobile device corresponding to the second time. As such, according to certain embodiments, the second change indicates a speed at which the mobile device has traveled during the time interval.

At the process 216, the computing device determines whether the third change satisfies the third predetermined condition. For example, the third predetermined condition indicates a rate at which the mobile device is expected to travel while driving. According to some embodiments, the third predetermined condition is determined based on historical sensor data of other users. For example, the historical sensor data includes location data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes location data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the third predetermined condition is tailored to the user of the mobile device. For example, the third predetermined condition is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM 9 AM and 5 PM - 6 PM), 5 days (Mondays to Fridays) a week, the third predetermined condition is determined based upon the location data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the third predetermined condition is determined based upon the location data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the third predetermined condition is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical location data and/or information received from the user. According to some embodiments, the third predetermined condition is defined and provided by the insurer associated with a vehicle of the user.

At the process 218, the fourth change in the magnetometer data during the time interval between the first time and the second time is determined by comparing the first magnetometer data and the second magnetometer data. For example, the fourth change indicates a change in directional position of the mobile device (e.g., a direction where the mobile device is facing) during the time interval. According to some embodiments, the first magnetometer data is used to detect a first directional position of the mobile device corresponding to the first time, and the second magnetometer data is used to detect a second directional position of the mobile device corresponding to the second time. As such, according to certain embodiments, the fourth change indicates a change in the direction of the mobile device.

At the process 220, the computing device determines whether the fourth change satisfies the fourth predetermined condition. For example, the fourth predetermined condition indicates one or more changes in the direction of the mobile device that are expected when the mobile device is in a vehicle while driving. According to some embodiments, the fourth predetermined condition is determined based on historical sensor data of other users. For example, the historical sensor data includes magnetometer data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes magnetometer data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the fourth predetermined condition is tailored to the user of the mobile device. For example, the fourth predetermined condition is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM - 9 AM and 5 PM - 6 PM), 5 days (Mondays to Fridays) a week, the fourth predetermined condition is determined based upon the magnetometer data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the fourth predetermined condition is determined based upon the magnetometer data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the fourth predetermined condition is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical magnetometer data and/or information received from the user. According to some embodiments, the fourth predetermined condition is defined and provided by the insurer associated with a vehicle of the user.

At the process 222, the computing device determines whether all of the first, second, third, and fourth predetermined conditions are satisfied. In other words, the computing device determines if the changes in linear acceleration, angular velocity, speed, and direction of the mobile device of the user satisfy the predetermined conditions that are expected when the mobile device is in a vehicle.

At the process 224, in response to determining that all of the first, second, third, and fourth predetermined conditions are satisfied, the computing device determines that the mobile device was indeed in a vehicle that the user is driving during the time interval and that the sensor data received during the time interval is reliable. In other words, the application is working properly to transmit the sensor data in response to the mobile device being in the vehicle that the user is driving, according to the illustrative embodiment.

Referring back to the process 222, the computing device further determines whether none of the first, second, third, and fourth predetermined conditions are satisfied. In other words, the computing device determines if none of the changes in linear acceleration, angular velocity, speed, and direction of the mobile device of the user satisfy an of the predetermined conditions that are expected when the mobile device is in a vehicle.

At the process 226, in response to determining that all of the first, second, third, and fourth predetermined conditions are not satisfied, the computing device determines that the mobile device was not in a vehicle during the time interval when the first set of sensor data and the second set of sensor data were generated and/or collected and the sensor data received during the time interval is unreliable. In other words, the application is not working properly to transmit the sensor data in response to the mobile device being in the vehicle that the user is driving, according to the illustrative embodiment.

At the process 228, in response to the determination that the mobile device is not in the vehicle that the user is driving during the time interval, the notification is transmitted to the mobile device indicating that the application does not work properly. In other words, according to some embodiments, the set of sensor data does not adequately represent the driving behavior of the user. As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

At the process 230, the computing device updates or adjusts an amount of insurance discount. According to certain embodiments, the user receives an initial discount from an insurer for installing the application and authorizing the application to transmit the set of sensor data collected and/or generated by one or more sensors of the mobile device in response to the mobile device being in the vehicle that the user is driving. For example, as discussed above, the sensor data includes information related to a user activity, such as driving behavior. As an example, the sensor data provided by the application related to the driving behavior of the user is used to generate alert notifications to the user that may reduce the likelihood of a collision or other damage occurring to the vehicle or the user. In other words, because the use of the application functions to mitigate or prevent driving risks upon which an insurance policy is partially based, the insurer provides an additional discount to the user for installing and continuing to use the application according to some embodiments. As such, for example, in response to determining that the application is not working properly to provide the sensor data, the insurance discounts, premiums, rates, points, or programs is calculated, updated, and/or adjusted. In certain embodiments, the updated or adjusted insurance discount, premiums, rates, points, or programs is communicated to the user for the user’s review, modification, and/or approval.

At the process 232, the computing device transmits a notification to the user of the mobile device indicating that the amount of insurance discount has been updated or adjusted according to some embodiments. For example, the notification further includes one or more corrective actions that the user may take in order to qualify for one or more insurance discounts.

As discussed above and further emphasized here, FIGS. 2A, 2B and 2C are merely examples, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In one embodiment, if one or more predetermined conditions (e.g., one predetermined condition, two predetermined conditions, three predetermined conditions, or all four predetermined conditions) of the first, second, third, and fourth predetermined conditions are satisfied, the process 224 is performed, and if none of the first, second, third, and fourth predetermined conditions are satisfied, the processes 226, 228, 230, and 232 are performed. In another embodiment, if all predetermined conditions of the first, second, third, and fourth predetermined conditions are satisfied, the process 224 is performed, and if one or more predetermined conditions (e.g., one predetermined condition, two predetermined conditions, three predetermined conditions, or all four predetermined conditions) are not satisfied, the processes 226, 228, 230, and 232 are performed.

In yet another embodiment, if at least two predetermined conditions (e.g., two predetermined conditions, three predetermined conditions or all four predetermined conditions) of the first, second, third, and fourth predetermined conditions are satisfied, the process 224 is performed, and if at least three predetermined conditions (e.g., three predetermined conditions or all four predetermined conditions) of the first, second, third, and fourth predetermined conditions are not satisfied, the processes 226, 228, 230, and 232 are performed. In yet another embodiment, if at least three predetermined conditions (e.g., three predetermined conditions or all four predetermined conditions) of the first, second, third, and fourth predetermined conditions are satisfied, the process 224 is performed, and if at least two predetermined conditions (e.g., two predetermined conditions, three predetermined conditions or all four predetermined conditions) of the first, second, third, and fourth predetermined conditions are not satisfied, the processes 226, 228, 230, and 232 are performed.

According to some embodiments, receiving the first set of sensor data from the application installed on the mobile device of the user in the process 102 as shown in FIG. 1 is performed by the process 202 as shown in FIG. 2A. According to certain embodiments, receiving the second set of sensor data from the application installed on the mobile device of the user in the process 104 as shown in FIG. 1 is performed by the process 204 as shown in FIG. 2A. According to some embodiments, determining whether the mobile device is in a vehicle that the user is driving in the process 106 as shown in FIG. 1 is performed by the processes 206-208 as shown in FIG. 2A, the processes 210-220 as shown in FIG. 2B, and the process 222 as shown in FIG. 2C. According to certain embodiments, transmitting a notification to the mobile device indicating that the application does not work properly in the process 108 is performed by the process 228 as shown in FIG. 2C.

FIGS. 3A, 3B and 3C are simplified diagrams showing a method 300 for verifying a reliability of sensor data received from a mobile device of a user according to certain embodiments of the present disclosure. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In the illustrative embodiment, the method 300 is performed by a computing device (e.g., a server 406 that is communicatively coupled to the mobile device). However, it should be appreciated that, in some embodiments, some of the method 300 is performed by the mobile device.

The method 300 includes process 302 for receiving a first set of sensor data at a first time from an application installed on a mobile device of a user, process 304 for receiving a second set of sensor data at a second time from the application, process 306 for comparing second accelerometer data of the second set of the sensor data with first accelerometer data of the first set of the sensor data to determine a first change during a time interval between the first time and the second time, process 308 for determining whether the first change is within a first predetermined range, process 310 for comparing second gyroscope data of the second set of the sensor data with first gyroscope data of the first set of the sensor data to determine a second change during the time interval, process 312 for determining whether the second change is within a second predetermined range, process 314 for comparing second location data of the second set of the sensor data with first location data of the first set of the sensor data to determine a third change during the time interval, process 316 for determining whether the third change is within a third predetermined range, process 318 for comparing second magnetometer data of the second set of the sensor data with first magnetometer data of the first set of the sensor data to determine a fourth change during the time interval, process 320 for determining whether the fourth change is within a fourth predetermined range, process 322 for determining whether all of the first, second, third, fourth changes are within its respective predetermined range or all of the first, second, third, fourth changes are not within its respective predetermined range, process 324 for determining that the mobile device is in the vehicle that the user is driving during the time interval in response to determining that the all of the first, second, third, fourth changes are within its respective predetermined range, process 326 for determining that the mobile device is not in the vehicle that the user is driving during the time interval in response to determining that the all of the first, second, third, fourth changes are outside of its respective predetermined range, process 328 for transmitting a first notification to the mobile device indicating that the application does not work properly in response to the mobile device not being in the vehicle that the user is driving during the time interval, process 330 for updating or adjusting an amount of insurance discount, and process 332 for transmitting a second notification to the mobile device indicating that the amount of insurance discount has been updated or adjusted.

Although the above has been shown using a selected group of processes for the method, there can be many alternatives, modifications, and variations. For example, some of the processes may be expanded and/or combined. Other processes may be inserted to those noted above. Depending upon the embodiment, the sequence of processes may be interchanged with others replaced. For example, although the method 100 is described as performed by the computing device above, some or all processes of the method are performed by any computing device or a processor directed by instructions stored in memory. As an example, some or all processes of the method are performed according to instructions stored in a non-transitory computer-readable medium.

Specifically, at the process 302, the first set of sensor data includes one or more types of sensor data that was collected and/or generated by one or more sensors of the mobile device according to some embodiments. For example, the one or more types of sensor data include a first type for accelerometer data, a second type for gyroscope data, a third type for location data, and a fourth type for magnetometer data. The application that is installed on the mobile device is configured to transmit a first set of sensor data. For example, the application broadcasts the first set of sensor data to be received by nearby devices and/or directly transmits the first set of sensor data to a destination computing device (e.g., a server that is communicatively coupled to the mobile device). In response, the computing device receives the first set of sensor data at the first time.

In the illustrative embodiment, at the time when the application was installed on the mobile device of the user, the application is configured to transmit one or more types of sensor data in response to a determination that the mobile device is in the vehicle that the user is driving. In such embodiment, the first set of sensor data includes information related to a user activity (e.g., driving behavior). As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

According to some embodiments, the first set of sensor data indicative of the user driving behavior is collected from one or more sensors associated with the user’s mobile device. For example, the one or more sensors include any type and number of accelerometers, gyroscopes, magnetometers, location sensors (e.g., GPS sensors), and/or any other suitable sensors that measure the state and/or movement of the mobile device. In certain embodiments, the first set of sensor data is collected continuously or at predetermined time intervals. According to certain embodiments, the first set of sensor data is collected based on a triggering event. For example, the first set of sensor data is collected when each sensor has acquired a threshold amount of sensor measurements. In other words, the sensor measurements may indicate that the mobile device is in a moving vehicle.

According to certain embodiments, the application is configured to transmit the first set of sensor data periodically every first predetermined time interval when the application is triggered by a predetermined event. In other words, the application may work properly in the background but may not transmit any sensor data until the predetermined event occurs. As an example, this reduces a battery power consumption and preserves battery life. For example, as discussed above, the predetermined event is a driving event. According to certain embodiments, the application determines the driving event based on the sensor data collected or generated by the mobile device. Additionally or alternatively, the application receives an input from the user that indicates that the user is driving according to certain embodiments. However, it should be appreciated that, in some embodiments, the application periodically transmits sensor data every predetermined time interval.

At the process 304, the application that is installed on the mobile device is configured to transmit the second set of sensor data that was collected and/or generated by one or more sensors of the mobile device according to some embodiments. For example, the application broadcasts the second set of sensor data to be received by nearby devices and/or directly transmits the second set of sensor data to a destination computing device (e.g., a server that is communicatively coupled to the mobile device). In response, the computing device receives the second set of sensor data at the second time. In the illustrative embodiment, the second set of sensor data is a set of sensor data that is received from the mobile device by the computing device subsequent to receiving the first set of sensor data. In other words, the second time follows the first time by a time interval. It should be appreciated that, in certain embodiments, the second set of sensor data includes sensor data that has been collected or generated from the same sensors of the mobile device that generated the first set of sensor data.

According to certain embodiments, the second set of sensor data includes information related to a user activity (e.g., driving behavior). As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

According to some embodiments, the second set of sensor data indicative of the user driving behavior is collected from one or more sensors associated with the user’s mobile device. For example, the one or more sensors include any type and number of accelerometers, gyroscopes, magnetometers, location sensors (e.g., GPS sensors), and/or any other suitable sensors that measure the state and/or movement of the mobile device. According to certain embodiments, the second set of sensor data is collected based on a triggering event. As discussed above, in the illustrative embodiment, the application is configured to transmit a set of sensor data when the application is triggered by driving event (i.e., the predetermined event). According to certain embodiments, the application determines the driving event based at least upon sensor data collected and/or generated by one or more sensors of the mobile device and/or user input. In other words, the application may work properly in the background and may not transmit any sensor data until the predetermined event occurs. As an example, this reduces a battery power consumption and preserves battery life.

At the processes 306, 308, 310, 312, 314, 316, 318, and 320, the computing device determines whether the mobile device is in a vehicle that the user is driving during a time interval between the first time and the second time based at least upon the first set of sensor data and the second set of sensor data received from the mobile device. As discussed above, when the application is initially installed on the mobile device, the application is configured to only transmit the sensor data that was collected and/or generated by the one or more sensors of the mobile device while the mobile device is in a vehicle that the user is driving. In other words, theoretically, the sensor data that was received from the application should represent sensor data that was collected and/or generated by the mobile device while the mobile device was in a vehicle. However, in real life, the sensor data received from the application may not be reliable for various reasons. To verify that the application is working properly and that the set of sensor data received from the application is reliable, the computing device determines whether the first set of sensor data and the second set of sensor data were generated and/or collected while the mobile device was indeed in a vehicle.

In the illustrative embodiment, the first sensor data includes first accelerometer data corresponding to the first time, first gyroscope data corresponding to the first time, first location data corresponding to the first time, and first magnetometer data corresponding to the first time. The second sensor data includes second accelerometer data corresponding to the second time, second gyroscope data corresponding to the second time, second location data corresponding to the second time, and second magnetometer data corresponding to the second time.

Specifically, at the process 306, the first change in the accelerometer data during the time interval between the first time and the second time is determined by comparing the first accelerometer data and the second accelerometer data. For example, the first change indicates a change in movement of the mobile device during the time interval. According to some embodiments, the first accelerometer data is used to detect a first linear acceleration of movement of the mobile device corresponding to the first time, and the second accelerometer data is used to detect a second linear acceleration of movement of the mobile device corresponding to the second time. As such, according to certain embodiments, the first change indicates a change in the linear acceleration of movement of the mobile device.

At the process 308, the computing device determines whether the first change is within the first predetermined range. For example, the first predetermined range indicates a range of movements of the mobile device that is expected when the mobile device is in a vehicle while driving. According to some embodiments, the first predetermined range is determined based on historical sensor data of other users. For example, the historical sensor data includes accelerometer data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes accelerometer data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the first predetermined range is tailored to the user of the mobile device. For example, the first predetermined range is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM -- 9 AM and 5 PM --- 6 PM), 5 days (Mondays to Fridays) a week, the first predetermined range is determined based upon the accelerometer data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the first predetermined range is determined based upon the accelerometer data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the first predetermined range is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical accelerometer data and/or information received from the user. According to some embodiments, the first predetermined range is defined and provided by the insurer associated with a vehicle of the user.

At the process 310, the second change in the gyroscope data during the time interval between the first time and the second time is determined by comparing the first gyroscope data and the second gyroscope data. For example, the second change indicates a change in rotational position or angular velocity of the mobile device during the time interval. According to some embodiments, the first gyroscope data is used to detect a first rotational position of the mobile device corresponding to the first time, and the second gyroscope data is used to detect a second rotational position of the mobile device corresponding to the second time. As such, according to certain embodiments, the second change indicates a change in the angular velocity of the mobile device.

At the process 312, the computing device determines whether the second change is within the second predetermined range. For example, the second predetermined range indicates a range of angular velocity of the mobile device that is expected when the mobile device is in a vehicle while driving. According to some embodiments, the second predetermined range is determined based on historical sensor data of other users. For example, the historical sensor data includes gyroscope data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes gyroscope data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the second predetermined range is tailored to the user of the mobile device. For example, the second predetermined range is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM - 9 AM and 5 PM - 6 PM), 5 days (Mondays to Fridays) a week, the second predetermined range is determined based upon the gyroscope data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the second predetermined range is determined based upon the gyroscope data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the second predetermined range is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical gyroscope data and/or information received from the user. According to some embodiments, the second predetermined range is defined and provided by the insurer associated with a vehicle of the user.

At the process 314, the third change in the location data (e.g., GPS data) during the time interval between the first time and the second time is determined by comparing the first location data and the second location data. For example, the third change indicates a change in location of the mobile device during the time interval. According to some embodiments, the first location data is used to detect a first location of the mobile device corresponding to the first time, and the second location data is used to detect a second location of the mobile device corresponding to the second time. As such, according to certain embodiments, the second change indicates a speed at which the mobile device has traveled during the time interval.

At the process 316, the computing device determines whether the third change is within the third predetermined range. For example, the third predetermined range indicates a range of speed at which the mobile device is expected to travel while driving. According to some embodiments, the third predetermined range is determined based on historical sensor data of other users. For example, the historical sensor data includes location data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes location data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the third predetermined range is tailored to the user of the mobile device. For example, the third predetermined range is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM - 9 AM and 5 PM - 6 PM), 5 days (Mondays to Fridays) a week, the third predetermined range is determined based upon the location data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the third predetermined range is determined based upon the location data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the third predetermined range is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical location data and/or information received from the user. According to some embodiments, the third predetermined range is defined and provided by the insurer associated with a vehicle of the user.

At the process 318, the fourth change in the magnetometer data during the time interval between the first time and the second time is determined by comparing the first magnetometer data and the second magnetometer data. For example, the fourth change indicates a change in directional position of the mobile device (i.e., a direction where the mobile device is facing) during the time interval. According to some embodiments, the first magnetometer data is used to detect a first directional position of the mobile device corresponding to the first time, and the second magnetometer data is used to detect a second directional position of the mobile device corresponding to the second time. As such, according to certain embodiments, the fourth change indicates a change in the direction of the mobile device.

At the process 320, the computing device determines whether the fourth change is within the fourth predetermined range. For example, the fourth predetermined range indicates a range of direction of the mobile device that are expected when the mobile device is in a vehicle while driving. According to some embodiments, the fourth predetermined range is determined based on historical sensor data of other users. For example, the historical sensor data includes magnetometer data generated and/or collected by one or more mobile devices that have been verified to be positioned in a vehicle. Additionally or alternatively, the historical sensor data includes magnetometer data collected and/or generated by other mobile devices of other users who has similar demographic information as the user. For example, the demographic information may include, but not limited to, age, race, ethnicity, gender, marital status, income, education, and/or employment. In certain embodiments, the historical sensor data is defined and provided by an insurer associated with a vehicle of the user. It should be appreciated that, the historical sensor data is stored in the database (e.g., a data storage 436) of the computing device (e.g., a server 406), according to some embodiments.

According to some embodiments, the fourth predetermined range is tailored to the user of the mobile device. For example, the fourth predetermined range is based upon a life routine or pattern of the user (e.g., a driving pattern) at a particular time of a day, a particular time of a week, a particular time of a month, a particular time of a year, or any combination thereof. In some embodiments, these user data are obtained directly from the user or determined and/or predicted based on the previous sensor data of the user. For example, if the user typically drives 20 miles to and from work between traffic hours (e.g., 8 AM - 9 AM and 5 PM - 6 PM), 5 days (Mondays to Fridays) a week, the fourth predetermined range is determined based upon the magnetometer data previously collected and/or generated during those time periods. It should be appreciated that, in some embodiments, the fourth predetermined range is determined based upon the magnetometer data collected and/or generated by other mobile devices of other users who regularly travels or commutes the similar routes during those same time periods.

According to certain embodiments, the fourth predetermined range is determined using one or more machine learning algorithms, programs, modules, or models based upon the historical magnetometer data and/or information received from the user. According to some embodiments, the fourth predetermined range is defined and provided by the insurer associated with a vehicle of the user.

At the process 322, the computing device determines whether all of the first, second, third, and fourth changes are within the first, second, third, and fourth predetermined ranges, respectively. In other words, the computing device determines if the changes in linear acceleration, angular velocity, speed, and direction of the mobile device of the user is within the predetermined ranges that are expected when the mobile device is in a vehicle.

At the process 324, in response to determining that all of the first, second, third, and fourth changes are within the first, second, third, and fourth predetermined ranges, respectively, the computing device determines that the mobile device was indeed in a vehicle that the user is driving during the time interval and that the sensor data received during the time interval is reliable. In other words, the application is working properly to transmit the sensor data in response to the mobile device being in the vehicle that the user is driving, according to the illustrative embodiment.

Referring back to the process 322, the computing device further determines whether all of the first, second, third, and fourth changes are outside of the first, second, third, and fourth predetermined ranges, respectively. In other words, the computing device determines if none of the changes in linear acceleration, angular velocity, speed, and direction of the mobile device of the user are within the predetermined ranges that are expected when the mobile device is in a vehicle.

At the process 326, in response to determining that all of the first, second, third, and fourth changes are outside of the first, second, third, and fourth predetermined ranges, respectively, the computing device determines that the mobile device was not in a vehicle during the time interval when the first set of sensor data and the second set of sensor data were generated and/or collected and the sensor data received during the time interval is unreliable. In other words, the application is not working properly to transmit the sensor data in response to the mobile device being in the vehicle that the user is driving, according to the illustrative embodiment.

At the process 328, in response to the determination that the mobile device is not in the vehicle that the user is driving during the time interval, the notification is transmitted to the mobile device indicating that the application does not work properly. In other words, according to some embodiments, the set of sensor data does not adequately represent the driving behavior of the user. As an example, the user driving behavior represents a manner in which the user has operated a vehicle. For example, the user driving behavior indicates the user’s driving habits and/or driving patterns.

At the process 330, the computing device updates or adjusts an amount of insurance discount. According to certain embodiments, the user receives an initial discount from an insurer for installing the application and authorizing the application to transmit the set of sensor data collected and/or generated by one or more sensors of the mobile device in response to the mobile device being in the vehicle that the user is driving. For example, as discussed above, the sensor data includes information related to a user activity, such as driving behavior. As an example, the sensor data provided by the application related to the driving behavior of the user is used to generate alert notifications to the user that may reduce the likelihood of a collision or other damage occurring to the vehicle or the user. In other words, because the use of the application functions to mitigate or prevent driving risks upon which an insurance policy is partially based, the insurer provides an additional discount to the user for installing and continuing to use the application according to some embodiments. As such, for example, in response to determining that the application is not working properly to provide the sensor data, the insurance discounts, premiums, rates, points, or programs is calculated, updated, and/or adjusted. In certain embodiments, the updated or adjusted insurance discount, premiums, rates, points, or programs is communicated to the user for the user’s review, modification, and/or approval.

At the process 332, the computing device transmits a notification to the user of the mobile device indicating that the amount of insurance discount has been updated or adjusted according to some embodiments. For example, the notification further includes one or more corrective actions that the user may take in order to qualify for one or more insurance discounts.

According to some embodiments, receiving the first set of sensor data from the application installed on the mobile device of the user in the process 102 as shown in FIG. 1 and/or the process 202 as shown in FIG. 2A is performed by the process 302 as shown in FIG. 3A. According to certain embodiments, receiving the second set of sensor data from the application installed on the mobile device of the user in the process 104 as shown in FIG. 1 and/or the process 204 as shown in FIG. 2A is performed by the process 304 as shown in FIG. 3A. According to some embodiments, determining whether the mobile device is in a vehicle that the user is driving in the process 106 as shown in FIG. 1 and/or the processes 206-208 as shown in FIG. 2A, the processes 10-220 as shown in FIG. 2B, and the process 222 as shown in FIG. 2C is performed by the processes 306-308 as shown in FIG. 3A, the processes 310-320 as shown in FIG. 3B, and the process 322 as shown in FIG. 3C. According to certain embodiments, transmitting a notification to the mobile device indicating that the application does not work properly in the process 108 and/or the process 228 as shown in FIG. 2C is performed by the process 328 as shown in FIG. 3C.

As discussed above and further emphasized here, FIGS. 3A, 3B and 3C are merely examples, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In one embodiment, if one or more changes (e.g., one change, two changes, three changes, or all four changes) of the first, second, third, and fourth changes are within one or more corresponding predetermined ranges, the process 324 is performed, and if none of the first, second, third, and fourth changes are within their corresponding predetermined ranges, the processes 326, 328, 330, and 332 are performed. In another embodiment, if all changes of the first, second, third, and fourth changes are within their corresponding predetermined ranges, the process 324 is performed, and if one or more changes (e.g., one change, two changes, three changes, or all four changes) are not within (e.g., outside) their corresponding predetermined ranges, the processes 326, 328, 330, and 332 are performed.

In yet another embodiment, if at least two changes (e.g., two changes, three changes or all four changes) of the first, second, third, and fourth changes are within their corresponding predetermined ranges, the process 324 is performed, and if at least three changes (e.g., three changes or all four changes) of the first, second, third, and fourth changes are not within (e.g., outside) their corresponding predetermined ranges, the processes 326, 328, 330, and 332 are performed. In yet another embodiments, if at least three changes (e.g., three changes or all four changes) of the first, second, third, and fourth changes are within their corresponding ranges, the process 324 is performed, and if at least two changes (e.g., two changes, three changes or all four changes) of the first, second, third, and fourth changes are not within (e.g., outside) their corresponding ranges, the processes 326, 328, 330, and 332 are performed.

II. One or More Systems for Determining a Status of a Mobile Device According to Certain Embodiments

FIG. 4 is a simplified diagram showing a system for verifying a reliability of sensor data received from a mobile device of a user according to certain embodiments of the present disclosure. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In the illustrative embodiment, the system 400 includes a mobile device 402, a network 404, and a server 406. Although the above has been shown using a selected group of components for the system, there can be many alternatives, modifications, and variations. For example, some of the components may be expanded and/or combined. Other components may be inserted to those noted above. Depending upon the embodiment, the arrangement of components may be interchanged with others replaced.

In various embodiments, the system 400 is used to implement the method 100, the method 200, and/or the method 300. According to certain embodiments, the mobile device 402 is communicatively coupled to the server 406 via the network 404. As an example, the mobile device 402 includes one or more processors 416 (e.g., a central processing unit (CPU), a graphics processing unit (GPU)), a memory 418 (e.g., random-access memory (RAM), read-only memory (ROM), flash memory), a communications unit 420 (e.g., a network transceiver), a display unit 422 (e.g., a touchscreen), and one or more sensors 424 (e.g., an accelerometer, a gyroscope, a magnetometer, a location sensor). For example, the one or more sensors 424 are configured to generate sensor data. According to some embodiments, the data are collected continuously, at predetermined time intervals, and/or based on a triggering event (e.g., when each sensor has acquired a threshold amount of sensor measurements).

In some embodiments, the mobile device 402 is operated by the user. For example, the user installs an application associated with an insurer on the mobile device 402 and allows the application to communicate with the one or more sensors 424 to collect sensor data. According to some embodiments, the application collects the sensor data continuously, at predetermined time intervals, and/or based on a triggering event (e.g., when each sensor has acquired a threshold amount of sensor measurements). In certain embodiments, the sensor data represents the user’s activity/behavior, such as the user driving behavior, in the method 100, the method 200, and/or the method 300.

According to certain embodiments, the collected data are stored in the memory 418 before being transmitted to the server 406 using the communications unit 422 via the network 404 (e.g., via a local area network (LAN), a wide area network (WAN), the Internet). In some embodiments, the collected data are transmitted directly to the server 406 via the network 404. In certain embodiments, the collected data are transmitted to the server 406 via a third party. For example, a data monitoring system stores any and all data collected by the one or more sensors 424 and transmits those data to the server 406 via the network 404 or a different network.

According to certain embodiments, the server 406 includes a processor 430 (e.g., a microprocessor, a microcontroller), a memory 432, a communications unit 434 (e.g., a network transceiver), and a data storage 436 (e.g., one or more databases). In some embodiments, the server 406 is a single server, while in certain embodiments, the server 406 includes a plurality of servers with distributed processing. As an example, in FIG. 4 , the data storage 436 is shown to be part of the server 406. In some embodiments, the data storage 436 is a separate entity coupled to the server 406 via a network such as the network 404. In certain embodiments, the server 406 includes various software applications stored in the memory 432 and executable by the processor 430. For example, these software applications include specific programs, routines, or scripts for performing functions associated with the method 100, the method 200, and/or the method 300. As an example, the software applications include general-purpose software applications for data processing, network communication, database management, web server operation, and/or other functions typically performed by a server.

According to various embodiments, the server 406 receives, via the network 404, the sensor data collected by the one or more sensors 424 from the application using the communications unit 434 and stores the data in the data storage 436. For example, the server 406 then processes the data to perform one or more processes of the method 100, one or more processes of the method 200, and/or one or more processes of the method 300.

According to certain embodiments, the notification in response to the application being determined not working properly in the method 100, the method 200, and/or the method 300 is transmitted back to the mobile device 402, via the network 404, to be provided (e.g., displayed) to the user via the display unit 422.

In some embodiments, one or more processes of the method 100, one or more processes of the method 200, and/or one or more processes of the method 300 are performed by the mobile device 402. For example, the processor 416 of the mobile device 402 processes the data collected by the one or more sensors 424 to perform one or more processes of the method 100, one or more processes of the method 200, and/or one or more processes of the method 300.
